【Abstract】

<正>We study the fluid-structure interaction encountered in hydraulic fracturing.Simulating this process needs to take into account the interaction between a fracturing solid and the fluid flow in the crack.With the possible presence of a fluid lag,the evolving fluid front inside the crack and the crack front are constrained by a Kuhn-Tucker complementarity condition.Brute-force methods
